Continuing from where we left off, the protagonist, who know calls himself Tsukiō (translates to Moon King in Japanese), intimidates all the characters across the Primary Plaza and knocks out a few using Conqueror's Haki.
Batman (shocked and in his thoughts): How can he unlock a foreign power with ease? Could it be? It can't be? No, it has to be? He has to be one of those mortals!
Tsukiō (the protagonist): "slowly deactivates Conqueror's Haki" Let them go, you Rogue bastards! "rushes towards the villains to fight back"
Mordo (nearly passed out but still consious): You can't stop us from capturing you, foreign mortal! "Conjures a sword using Eldritch magic and goes to attack Tsukiō"
Tsukiō: "somehow creates a portal using Eldritch magic (the same way that Doctor Strange does it in the MCU films) and goes through it"
Mordo: (mind-blowingly shocked) HOW?!
Magik: first haki, and now eldritch magic? How?
Avdol: This mortal is something else.
Batman: he is something. Something nigh-nonexistent.
Tsukiō: "is behind Mordo" KOKUSEN!!! "Uses Black Flash (Jujutsu Kaisen) on Mordo"
Mordo: "gets injured, knocked on the ground, and unconscious"
Everyone else: "is shocked af, wondering how did he use 3 completely different powers from 3 completely different world"
Tsukiō: who's next?! "Says it while looking at Rui, and accidentally uses Shunpo aka Flash Step (Bleach)"
Rui: IMPOSSIBLE!!!
Tsukiō: KOKUSEN!!!! "uses Black Flash again, but this time, his arm is uncontrollably coated in Armament Haki"
Rui: "is knocked out too"
Batman, Avdol, and Magik are all mind-blown, wondering how in the living hell does a mortal use all this powers from universes that not only are vastly different from one another, but also he is not a part of.
Kizaru: Oh my! Oh my! Guess I have no choice but to escape. "Uses his light logia devil fruit powers to escape"
Tsukiō: get back here! "Falls down from his injures and the overload of his powers"
Batman: I got the boy. Capture the remaining villains! "Runs to Tsukiō" Kid, you ok?
Tsukiō: I'm fine. Just a strain.
Batman: here. Let me help you out.
[At Reverse Senzu Hospital (named after RCT from JJK and Senzu Beans from Dragon Ball)]
Shoko Ieiri (from Jujutsu Kaisen): The kid's alright. His body simply haven't used to his immense powers. But still, I can't believe a human like him has ever ex....
Batman: "Cuts her off with a cough" thanks for the healing, Ms.Ieiri. The boy's mine for the caring.
Tsukiō: Yeah. Thank you, Ms. Shoko.
Shoko: Don't mention it. "leaves"
Tsukiō: "after Shoko leaves" how did I do all that?
Batman: I think I know how did you do it. You are a Systemer
Tsukiō: A what now?
Batman: a portmanteau of system and sorcerer. You are one of the very few humans registered to the Hyper Ability Education (HAE) System. It's designed to allow mortals like you to naturally learn various abilities from all fictional universes with ease. While some of us fictional characters can use abilities from other worlds in certain conditions, only Systemers can naturally learn it and use it with no limit of location or identity. When they awaken it, they initially use multiple abilities that they haven't accessed or learned yet. think of it as an adrenaline rush.
Tsukiō: I see. Are there other Systemer like me living in the MKA or in any of the worlds linked to it?
Batman: while possibly, you're the first systemer I have ever seen. And not many characters know about it, as it is a secret.
Tsukiō: understood. So, I guess this is how I use all these po...."suddenly gets a brain rush" WHAT IS THIS?
Batman: Tsukiō! What's wrong?
Tsukiō: I feel like... a memory of mine is coming back.... sprinting to my soul.
Tsukiō experiences what he calls a "Memory Payback", where he regains a memory of his in various random moments. In this case, he remembers walking to a mosque and praying there while making dua right after
Tsukiō: I used to be.... a Muslim... back then.
Batman: it's probably one of the things you used to be before you moved in here and you still are one of them.
Tsukiō: Subhannallah! Ok. I have decided.
Batmam: decided what?
Tsukiō: you said that the only way to return home is through the Ultimate Fantasy Tournament, right?
Batman: yes. Are you trying to participate and win?
Tsukiō: yes. If I was a main character, then this is my motive. I will regain my memories and return to my world. Maybe Allah sent me here to be tested, and if so, then so be it. That is my purpose right now.
Batman: "grins clearly" you got guts and potential. Fine then, let me help you.
Tsukiō: great. Works for me.
The chapter ends with Tsukiō and Batman shaking hands in respect and cooperation.
